土壤侵蚀模型研究综述

Overview on Soil Erosion Model Research

近年来 ,人们对土壤水蚀形成过程及其模拟进行了广泛研究 ,并针对不同研究对象与目的 ,建立了土壤水蚀的经验预报模型、物理过程模型和分布式模型。在对国内外一些主要的土壤水蚀模型进行评述的基础上 ,讨论土壤侵蚀模型研究与GIS技术和BP神经网络理论结合的发展趋势 ,同时结合土壤水蚀模型的开发和应用情况 ,提出了土壤侵蚀预报模型研究亟待解决的一些问题和我国土壤侵蚀预报模型研究的设想。

In recent years, the researchers did many studies on the process of water erosion and simulation. Based on the different study object and purpose, a lot of empirical models, physical process models and distributed models have been built up. This paper summarize the main soil erosion models in home and abroad, and discuss the last development of the studies on soil erosion model, which integrated with the GIS technologies and BP nerve network theories. According to the model's development and application, some problems to be solved urgently are raised, and more, the tentative plan of the study on soil erosion model in home is also pointed out.
